MONACO — Even though he matched his father in winning the Monaco Grand Prix, Nico Rosberg believes he's a long way from completing another father-and-son double by clinching the world title as well.

Rosberg kept his cool amid the chaos to win the crash-marred race on Sunday to give Mercedes its first victory of the season. The win also matched the feat of his father, Keke Rosberg, who won in Monaco in 1983 — a year after he won his only F1 title.
